In a reality-based world, states like Oregon where there's not much in the way of "diversity" ought to be resolutely Conservative. That also applies to Vermont, a leftist "paradise" in spite of being overwhelmingly white. I believe there's a large percentage of self-hating whites in such places, therefore "white guilt" contributes to the support of communism and its "religious" wing, islam.
In contrast, states like Texas and Mississippi embrace Conservatism perhaps because we see, on a daily basis, the disastrous effects of multiculturalism.
The Willamette Valley types see it, too. And Oregon’s liberals gravitate there. That big expanse of tranquility in Oregon probably only houses a scant tens of thousands.
